SPECIFKCATION forming part of Letters Patent No. 522,895, dated July 10,1894.

Application filed December 29, 1893. Serial No. 495,104- (NQ 11105913 To@ZZ whom it may concern,.-`

Be it known that I, FERDINAND J. HAGEN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements inCigarette-lVIachines, of which the following is a specification,reference being had therein to the accompanying drawings.

In the drawings, Figure l designates a side elevation of a cigarettemachine embodying my improvements; Fig. 2 a vertical section of thesame, taken on the line 2 2 of Fig. 1; Fig. 2 a detail view of theregulating cams. Fig. 3 is a vertical sectional View of thetobacco-feedin g and disintegratin g mechanism, some of the parts beingbroken away for the purpose of better illustration; Fig. 4 a detail planview of the swinging-frame carrying the chain rollers; Fig. 5 an endview of the machine. Fig. 6 is a detail view showing more clearly thearrangement of the pressure guidebars between the exit ends of the mainfeed- `This invention relates to that class of machines known as thecontinuous cigarette machines, and it has mainly for its object toprovide improved mechanism for uniformly feeding the tobacco to theforming-belt, said feeding mechanism being entirely automatic in itsaction, as more fully hereinafter appears.

A further object of this invention is to so arrange the filler-formingbelt that it may be readily removed and replaced without disturbing theother parts of the machine, whereby a material saving in time iseffected, as more fully hereinafter appears.

I will now proceed to describe the preferred construction for carryingout my invention, but it is understood that this construction may bedeparted from without departing from the spirit of the invention.

Referring to the drawings by letters, A designates the main frame of themachine and A a smaller frame mounted upon the table ofthe main frame atone end thereof; A designates a frame or casing mounted on the maintable between the sides of the frame A'.

A feed-belt a of the usual construction is suitably mounted adjacent tothe casing A" and is adapted Vto convey the tobacco to the mainfeed-belts b, which are mounted upon rollers b and are constructed ofcurved metallic links transversely pivoted togethenand extendingentirely across the face of the rollers.

As stated, the links are curved transversely, so as to fit the curvedfaces of the rollers, and

the rollers are provided with longitudinal grooves b in their faces forthe reception of the transverse hinges of the links.

The two rollers carrying the upper chain are mounted in a frameconsisting of two parallel side-bars c c, the shaft c of the frontroller being rigidly fixed in said arms and the roller being looselymounted on said shaft, while' the rear roller is fixed on its shaft cand said lshaft is journaled loosely in longitudinal slots in the endsof the arms c.

The ends of shaft c are extended outwardly beyond the arm c andjournaled loosely in boxes c3, which are free to work in vertical slotsformed in the frame A', thereby permitting said shaft c and itsrollerito vibrate vertically a limited distance; the boxes c3 arenormally heldl down in the lower ends of their slots by means ofcoil-springs c4 held in place by caps c5. The ends of shaft c are alsoextended and journaled 'in the sides of the frame A', thereby formingthe fulcrum or oscillating point of the side bars or levers c.

The rollers of the lower chain or belt b are mounted rigidly on theirshafts and the shafts are extended and journaled in the frame A', andthe upper belt or chain is driven in unison with the lower belt by meansof a gear d secured on one end of the rear lower shaft and meshing witha similar gear on the vibratable shaft c, the 'teeth of these gearsbeing sufficiently long to enable the upper gear to move vertically'ashort distance without beA coming disengaged from the lower gear.

The shaft of wheel d is driven by means of a large spur gear d2 securedon its opposite end outside of casing A', and this gear d2 is driven bya pinion d3 secured on a short shaft d4, whose inner end is journaled inthe casing A and whose outer end is journaled iu a bearing d5 mounted onthe upper end of a vertical shaft'd, hereinafter described.

Between the exit or rear ends of the chain belts are located a pair ofpressure guide bars e e', the former being carried by the levers or ICOframe-bars c, thereby being vertically vibratable, and the latter beingsecured at its ends rigidly to the frame A. These two bars are formedexactly alike in cross-section, their adjacent faces being fiat anddirectly in line with the adjacent faces of the belts, and their facesnext to the belts being transversely curved or concaved correspondinglyto the curvature of the rollers b and fitting nicely against the beltsas they pass around the rollers, the edges of the bars formed by thejunction of these two faces being sufficiently sharp to scrape or removethe tobacco from the chains and direct it between the two bars. The rearedges or faces of the bars are concaved to correspond to the curvatureof a roller or shaft e2 journaled in the frame a', directly to the rearof said bars, and driven by means of a belt e3, connecting a pulley e4,secured on one of its ends, to a larger pulley c5 secured on the end ofthe main shaft e6 journaled in the main table.

The shaft or roller e2 is provided in its surface with a series of shortpins or spikes, which pass close to the curved faces of bars ce andreceive the tobacco and deposit it in a chute or funnel f supportedbetween the side frames A.

The funnel f deposits the tobacco between a pair of rolls f f2, theformer of which is journaled stationarily in the frame A and is providedwith a smooth surface, and the other roll f 2 is journaled in the lowerends of swinging links f3 pivoted on the casing A. The roller f2 is keptresiliently pressed toward the roller f by means of springs f4 bearingagainst the lower end of links f3 and adjustably supported in socketsf5, mounted on a/suitable part of the frame, by means of set screws f6,these screws serving to vary the pressure exerted by the springs.

Supported between rolls ff2 is a scraperbarg, which is substantiallytriangular in shape and has its uppersharpened edge bearing upon thesurface of the smooth roll f to scrape the tobacco therefrom, While theface adjacent to the roll f2 is concaved to correspend with that roll.The lower side of the bar g is concaved to correspond with the curvature of a spiked-roller g', mounted in the frame A and driven by abelt g passing over a pulley g3 on the shaft of roller g and over thepulley c5 on the main shaft.

The roll f is driven by a vertical shaft h carrying a beveled gear h onits upper end which meshes with a similar 'gear h2 on the shaft of saidrollf, said shaft hzbeing driven by means of a beveled gear h3 securedon its lower end and meshing with a similar gear h4 on the main shaft.

The roll]c2 is driven at aspeed corresponding to the roll f by means ofsmall gears 71.5 h, secured on the adjacent ends of the shafts of saidrollers, the teeth of the gears being sufficiently long to allow theroll f2 to vibrate slightly without disengagement.

A funnelshaped casiug'iembraces the rolls f f2 and g and serves toconvey the disintegrated tobacco into a trough j supported along theside edge of the lnain table. The endless filler-forming belt 7c travelsin the trough j and serves to compress the tobacco into a continuousfiller 7c. To accomplish this the trough 7' is formed with a U-shapedgroove where it 'receives the tobacco from the chute t', as shown inFig. 3, and from that point its side edges are gradually turned over toacircular shape, as shown in Fig. 2, whereby the edges of the belt arefolded over upon the inclosed filler to compress it to the desireddensity or into'a rod of tobacco. The belt 7c is mounted upon pulleys k27c3 supported at the sides of the main vframe A, out of thc way of theother mechanism, the larger roller 7c3 being driven by a beveled gearZ194 secured on the inner end of its shaft and meshing with the beveledpinion h4 on the main shaft.

Upon the frame A, at a point between the pulleys k2 k3, is mounted abelt-tightener, which consists of a vertical arm Z pivoted at its lowerend on the frame and carrying a roller Z at its upper end, adapted tosupport the slack of the belt and keep it taut, said arm being readilyadjustable upon a suitable slotted segment Z2 by means of a lever nutZ3.

It will be observed that by lowering the belt-tightening arm the beltmay be readily slipped off its pulley `and out of the trough, and asreadily replaced Aby a new belt. This capability of readily replacingthe formingbelt is an essential feature as it saves valuable timeconsumed in changing the belt in the machines now in use. y

As the filler Zo leaves the forming belt it passes onto the paper m,which is unwound in the usual manner from arollm and passed through asuitable folding and pasting device m2, by which it is folded and pastedaround the filler.

Asuitable presser wheel m3 may be mounted at the inlet end of the folderto compress thc filler previously to being wrapped in the paper. Thepaper is carried through the former or folder by means of the usual beltn which Y is kept taut by means of a tightener n. Below the large pulley71,2, carrying belt n, is a frame n3 pivoted at one end and verticallyadjustable at its other end, by means of a cam n4, and carrying a seriesof rollers a5 adapted to bear upon the surface of the belt as it passesover pulley n2 and thereby serve to smooth the wrinkles out of the beltand prevent the same slipping. The means for pasting and folding thepaper around the filler are not claimed in this application.

The means for automatically regulating the feed is constructed asfollowsz-Adjustably connected to the extended end of one of the levers cis a vertical rod o which is pivotally connected at its lower end to avertical slide o working in vertical ways o" supported on the main frameA. The slide carries two cams o3 which are similarly constructed and IOOconnected together by a vertical pitman o4. The upper cam is connectedby a rod o to a pivoted lever p which has one of its ends forked so asto embrace pins p carried by a non-rotating collar fitted in a groove inthe hub of a friction wheelp?. The friction wheel p2 is connected toshaft d6 by means of a spline and feather, whereby it will be compelledto revolve with said shaft d6 but may be moved vertically thereon. Thefriction lwheel p2 bears against the face of a larger friction disk p3,carried by the short shaft dhereinbefore mentioned. The shaft d6 isdriven by means of a beveled pinion p4 which meshes with a similarpinion p5 on the main shaft. As shown in Fig. l, a rollerq is journaledin the frame A and adapted to bear upon the inner face of the frictiondisk p3 and thereby prevent the thrust of the friction wheel p2 fromdisplacingr said disk p3.

Journaled in hangersr, depending from the table of the main-frame is ashort shaft r carrying a gear wheel r2, meshing with a pinion 'r3 on themain shaft d6. One end of the shaft r extends through a vertical slot sformed in the slide 0 and carries a friction wheel's' at a point betweenthe two cams o3, the distance between the cams being slightly greaterthan the diameter of the said friction wheel s', as shown most clearlyin Fig. 2.

The operation of the machine is as follows: The opposing chain-belts breceive the tobacco from the feed-belt a and convey it between thepressure bars e e', slightly7 compressing it during its passage betweenthe belts. As will be seen, the adjacent faces of the bars e e must beformed substantially flat and must `always be exactly in line with theadjacent faces of the belts; should the upper bar not move exactly inunison with the upper belt and keep exactly in line with the working`face of the belt, the tobacco would either choke up between the beltsor be pulled ont too rapidly from between the bars by the spiked wheel,as is evident. This peculiar arrangement of the bars is necessary inorder that the feed be sensitive to the continually varying thickness ofthe tobacco. As the compressed body of tobacco is forced between thepressure guide bars e e', it is shredded and disintegrated by therapidly-revolving spiked roller c2 and deposited in the funnel f, whichin turn deposits it between the rollersf f2. The latter rollers, beingrapidly revolved in unison and in opposite directions and being heldresiliently together, again compress the tobacco and carry it downward;as the tobacco is carried downward it is scraped from the smooth roll byscraper-bar g and delivered to an opening t between the bar g and thecasingz', and as it falls through this opening the spiked wheel g',revolving rapidly, further shreds or combs the tobacco before deliveringit to the forming belt below. By means of this feeding and shreddingmechanism the tobacco is deposited in the belt uniformly, whereby thefiller will be of a uniform density throughout. As will be seen, thespring-pressed corrugated roller f2 compresses the tobacco againstscraper-barg until it is taken olf by the spiked roller.

Should the bodyof tobacco passing between the pressure bars vary inthickness, the mechanism shown and described will instantly adjustitself so as to increase or decrease the speed of the chain-belts,according as the body of tobacco becomes thinner or thicker, and therebycompensate for the varying thicknesses and maintain at all times auniform supply to the forming belt. As will be seen, to drive thechain-belts faster it is simply necessary that the friction wheel p2 bemoved nearer to the center of disk p3 and to decrease the speed of thebelts it is simply necessary to move said wheel p2 toward the peripheryof the disk p3. As the body of tobacco diminishes the upper pressure bare and the rear end of the frame carrying it will be depressed by springsc4 to conform to the thinner supply, and this action will raise the frod o and bring the lower cam into contact with the slowly-revolvingdisk s. When the lower cam o3 comes in contact with the disk of thewheel s it will be turned in the direction of the arrow shown in Fig. 2,which will, through the medium of pitman o", turn the upper cam in thedirection of the arrow shown and thereby raise rod o5 connected to thelever (p) controlling friction wheel p2; this action will raise thewheelp2 and move it nearer to the center of the disk p3 and thereby morerapidly drive the mechanism operating the chain-belts. When thethickness of the tobacco increases the operation will be the reverse ofthat just described-that is to say, the slide carrying the cams will belowered sufticiently to rest the upper cam on friction wheel s', whichwill reverse the movement of this cam and draw down the friction wheelp2 toward the periphery of disk p3, thereby diminishing the speed of thefeed-belts.

The only part of the periphery of each of the cams that comes intocontact with the friction-wheelis the enlarged part (between t and t2),shown most clearly in Fig. 2a. The pitman is so connected to the camsthat when the larger end t of the upper cani-surface is adjacent to thefriction-wheel the smaller end t2 of the lower cam-surface is adjacentto the opposite edge of the friction-wheel, and vice versa. When theupper cam drops upon the frictionwheel it is carried around in thedirection of the arrow and the speed of the chain-belts is graduallylowered; should the feed continue suiiiciently thick to keep said campressed against the friction wheel the cam will continue to turn untilthe smaller part p2of its surface is reached, at which point the turningof the cam and the downward movement of the slide carryngthe cam isarrested by the upper end of slot s coming into contact with shaft fr.This movement will bring the larger part t of the lower cam around intoposition, so that when the feed ICO IZO

becomes suiciently thin to raise the lower cam into contact with thefriction-wheel, the operation will be the reverse of that'justdescribed, the slot s serving also to limit the upward movement of theslide.
